To all whom t may concern.'

Be it known that I, OTTO J. Kul-Imre, a

citizen of the United States, residing at Akron, in the county ,ofSummit, State of Ohio, have invented certain new and useful Improvementsin Resilient Balls, ot which 1the[following is a specilication.

'My invention relates to improvements in resilient balls for use ingames wherein a strikingimplement is used and it has particularreference ,to ballsv adapted ltor .use

,in .the game of golf.

The particular purpose of the present invention is to provide a golfball that is l5 IHQI'e active, or responsive, `under 3a quick, hardbjlowthan existing types of golf balls, @Inl is also particularlyadaptedA for g ac` curate putting. d lMy invention is also directedtoward proriding ar golf yball, `which, in combination with Ithe aboveenumerated characteristics, possesses ,suiiicient symmetry, weight, andbalance to enable it" to maintain its direcf tion while it is in flight.VStill another object of the present invention lis `to provide a golf.ball which will function in the mannerabove set iorth Vand which may beproduced bythe manufacturer ata relatively low cost. Other objects,.together with the advan- `tages to be derived in the practice of my invention, will become 4apparent and Vthe `natureof the invention will be`fully understood when the following detailed descripings accompanyingandorming apart of this specification.

It is to be understood, however, that the present disclosure is merelyillustrative of apreterred ormof my invention and is not to be construedas limiting the scope orspirit of my invention unless such limitationsare indicated in the claims appended hereto, nor is the inventionlimited to golf balls, but may be applied in other shapes or forms.

In the drawings:

Figure 1 is a side elevational view of a golf ball constructed inaccordance with the principles of my invention, parts of the .ballheilig broken away and shown in section;

Figure 2 is a view partly in section, and partly in elevation,illustrating certain component parts of my invention; and

" tionis read in conjunction with tliedrawr,

Figure 3 is a sectional view of one ofthe elements of my invention.

The goltball of my invention preferably comp-rises a core l that-isiconstructed of line steel wire woundfinany suitable manner into the formof a hollow sphere. Preferably the sphere is formed from a? continuousAstrand of wire wound lin superposed convolutions so that ahighllylelasticor `resilient lbodyl is formed, which 'will quickly rebound whenstruck, thel air connedvwlithin the sphere acting as cushion.` Thesphere orcore l thus provided is `impreagnated with a" suitable coatingdesigned to `tie the convolutions together, contine the airifwithin thesphere, and to impart additional retion compositi-on of -rubberispreferred of a character suitable for `impregnating`the that ispossessed of resiliency,combined with suclentrigidity to prevent rtspermanent deiormation, and. a degree of weight sut jlicient toenable-ithfefball to maintain its material of the ylayer 2 --iscompressedand Vmaintained' under-compression in order to increase `itslinherent resiliency and to thereby. provide av highly reactive element`which will quickly respondand rebound trom a 'golf c lub,grepl-ac ingthe usual wound rubber Vwire andforming a hollow, 4air-ttght spherefound: in theI present typewo't golf ball. In

order te secure and maintain theproper de* gree of compression of Athelayer 2, it is provided, preferably, with apertures or cells 3 and 'iscovered Jwith a sheathrll. VThe apertures 8 may be arranged in the layer2 in any desired manner, but in this instance are formed through theentire thickness of the layer and substantially radially thereof. Thesheath l is formed of tightly wound thread or cord, such as linen, silk,or other material, wound so as tov provide a layer of the desiredthickness and iieXibility around the layer 2. Around the layer 2, aresilient covering 5 is provided of gutta percha, balata, or othersuitable material.

The foregoing structure provides for a golf` ball that is highly activewhen Struck inator of a golf ball, or other playing ball,

which is provided with a metallic member,

' such as the wound wire, rubber impregnated sphere, which is used toimpart both weight and resilience to the ball.' Prior golf balls haveused a metallic core, but, so far as I am aware, none has ever been usedin which thevmetallic core possessed a certain amount of resilience inand of itself. I am also the rst to use a rubber element in the ballvwhich is held under compression by a winding of core or thread, whichholds the rubber under compression. I am, therefore, entitled to a broadrange of equivalents in the construction of the appended claims.

. What I claim is:

1.- A golf ball comprising,a hollow wound wire sphere the'convolutionsthereof being impregnated with rubber, and an outer layer of rubber overthe sphere. 2. A ball comprising, a wound wire sphere impregnated withrubber and enclosing an air chamber therein. 3. A ball comprising, awound wire, hol-V low sphere, acellular envelope over the sphere', and awinding of substantially in extensible cord over the envelope holding itunder compression.

il. A ball comprising, a wound wire sphere said sphere being impregnatedwith rubber, a layer of rubber overthe sphere said layer being undercompression, and a winding of vcord over the layer maintaining the com-vpression therein.

5. A ball comprising, a wound wire sphere saidspherebeing impregnatedwith l rubber, a cellular envelope of rubber over the sphere said layerbeing under compres--r sion, and a winding 'of cord over the envelopemaintaining thecompression therein. A6. A ball comprising, a metallicwire sphere impregnated with rubber .and havingy resilient propertiesand enclosing an air chamber.

7. A ball comprising, a wound wire, liollow sphere impregnated withrubber and enclosing an air chamber, a layer of rubber about saidsphere, and means for maintaining the layer of rubber under compression.

S.`A ball comprising, a wound wire, hollow sphere impregnated withrubber and enclosing an air chamber, a layer of rubber about the sphere,a substantially inextensible cord sheath over. the rubber layer, and

a cover.

9. A ball comprising, a wound wire, hollow sphere impregnated withrubber and enclosing an air chamber, a layer of rubber over the spheresaid rubber being under compression, and a winding of cord over the saidlayery maintaining it under compression.

10. A ball having located within it a wound wire sphere, the intersticesof which are filled with rubber and a cover over the sphere. i

v11. A ball comprising a metallic sphere `composed of a plurality oflayers of wire impregnated with rubber .and confining an `air chambertherein.`

12. A ball comprising ay hollow metallic sphere composed of a continuousstrand of wirey wound insuperposed convolutioins, said sphere beingimpregnated with rubber, the

said sphere confining an air space therein.

13. A ball comprising a hollow air-tight sphere formed from a continuousstrand of wire wound in superposed convolutions and impregnated withrubber, and a cellular envelope over the sphere.

14. A ball comprising avhollow sphere consistingl of a strand of wirewound in superposed convolutions, a layer of rubber over the sphere,said layer being under com- `pression, and a winding of cord over thelayer maintaining the compression therein.

l15. Agolf ball comprising a wound wire, hollow sphere, the convolutionsof which are impregnated with rubber, and an outer cover.
